The document discusses the rise of social media and its intersection with politics and public opinion. It notes that social media use has grown dramatically in recent years and is now a major part of political communication. Politicians and publics now engage with each other through platforms like Facebook, Twitter, and YouTube. However, scholars are still working to understand the complex social media ecosystem and its effects. While social media was important in events like the Arab Spring, it can also potentially threaten democracy in some cases. The presenter aims to explore these issues.
